Congenital nasal pyriform aperture stenosis

SummaryThe congenital stenosis of pyriform aperture is an unusual cause of neonatal nasal obstruction. It is due to bony overgrowth of the nasal lateral process of the maxilla. Initially this narrowest part of nasal airway was considered an isolated deformity; subsequently the congenital Stenosis of pyriform aperture was thought to represent a microform of holoprosencephaly. In this report a male neonate had respiratory distress, cyclic cyanosis and apnea after delivery. The patient underwent surgical correction of pyriform stenosis by sublabial access. In the follow up, the patient had good evolution. The report of this deformity shows an important cause of neonatal nasal obstruction and its differential diagnosis with bilateral choanal atresia. Congenital stenosis of nasal pyriform aperture can be surgically corrected when necessary

Condrossarcoma de epiglote: relato de caso e revisão da literatura Epiglottis chondrosarcoma: review of the literature and report of one case

Condrossarcoma é o sarcoma mais freqüente da laringe. Sua incidência é maior na cartilagem cricóide do que nas outras cartilagens da laringe, sendo raro que ele se origine na epiglote. Relatamos no texto um caso de condrossarcoma originado na epiglote, no qual foi realizada laringectomia subtotal com crico-hioidopexia - e realizamos revisão da literatura.<br>Chondrosarcoma is the most frequent sarcoma of the larynx. It is more prevalent in the cricoid and less prevalent in the other laryngeal cartilages. Chondrosarcoma is rarely located in the epiglottis. We reported a case of epiglottis chondrosarcoma that was treated with a supracricoid laryngectomy with cricohyoidopexy
